--- id: release-notes title: "Release notes" --- ## Version 1.16 ### 🎭 Playwright Library #### Locator.WaitForAsync Wait for a locator to resolve to a single element with a given state. Defaults to the `state: 'visible'`. ```csharp var orderSent = page.Locator("#order-sent"); orderSent.WaitForAsync(); ``` Read more about [`method: Locator.waitFor`]. ### 🎭 Playwright Trace Viewer - run trace viewer with `npx playwright show-trace` and drop trace files to the trace viewer PWA - better visual attribution of action targets Read more about [Trace Viewer](./trace-viewer). ### Browser Versions - Chromium 97.0.4666.0 - Mozilla Firefox 93.0 - WebKit 15.4 This version of Playwright was also tested against the following stable channels: - Google Chrome 94 - Microsoft Edge 94 ## Version 1.15 ### 🖱️ Mouse Wheel By using [`Page.Mouse.WheelAsync`](https://playwright.dev/dotnet/docs/next/api/class-mouse#mouse-wheel) you are now able to scroll vertically or horizontally. ### 📜 New Headers API Previously it was not possible to get multiple header values of a response. This is now possible and additional helper functions are available: - [Request.AllHeadersAsync()](https://playwright.dev/dotnet/docs/next/api/class-request#request-all-headers) - [Request.HeadersArrayAsync()](https://playwright.dev/dotnet/docs/next/api/class-request#request-headers-array) - [Request.HeaderValueAsync(name: string)](https://playwright.dev/dotnet/docs/next/api/class-request#request-header-value) - [Response.AllHeadersAsync()](https://playwright.dev/dotnet/docs/next/api/class-response#response-all-headers) - [Response.HeadersArrayAsync()](https://playwright.dev/dotnet/docs/next/api/class-response#response-headers-array) - [Response.HeaderValueAsync(name: string)](https://playwright.dev/dotnet/docs/next/api/class-response#response-header-value) - [Response.HeaderValuesAsync(name: string)](https://playwright.dev/dotnet/docs/next/api/class-response/#response-header-values) ### 🌈 Forced-Colors emulation Its now possible to emulate the `forced-colors` CSS media feature by passing it in the [context options](https://playwright.dev/dotnet/docs/next/api/class-browser#browser-new-context-option-forced-colors) or calling [Page.EmulateMediaAsync()](https://playwright.dev/dotnet/docs/next/api/class-page#page-emulate-media). ### New APIs - [Page.RouteAsync()](https://playwright.dev/dotnet/docs/next/api/class-page#page-route) accepts new `times` option to specify how many times this route should be matched. - [Page.SetCheckedAsync(selector: string, checked: Boolean)](https://playwright.dev/dotnet/docs/next/api/class-page#page-set-checked) and [Locator.SetCheckedAsync(selector: string, checked: Boolean)](https://playwright.dev/dotnet/docs/next/api/class-locator#locator-set-checked) was introduced to set the checked state of a checkbox. - [Request.SizesAsync()](https://playwright.dev/dotnet/docs/next/api/class-request#request-sizes) Returns resource size information for given http request. - [Tracing.StartChunkAsync()](https://playwright.dev/dotnet/docs/next/api/class-tracing#tracing-start-chunk) - Start a new trace chunk. - [Tracing.StopChunkAsync()](https://playwright.dev/dotnet/docs/next/api/class-tracing#tracing-stop-chunk) - Stops a new trace chunk. ### Important ⚠ * ⬆ .NET Core Apps 2.1 are **no longer** supported for our CLI tooling. As of August 31st, 2021, .NET Core 2.1 is no [longer supported](https://devblogs.microsoft.com/dotnet/net-core-2-1-will-reach-end-of-support-on-august-21-2021/) and will not receive any security updates. We've decided to move the CLI forward and require .NET Core 3.1 as a minimum. ### Browser Versions - Chromium 96.0.4641.0 - Mozilla Firefox 92.0 - WebKit 15.0 ## Version 1.14 #### ⚡️ New "strict" mode Selector ambiguity is a common problem in automation testing. **"strict" mode** ensures that your selector points to a single element and throws otherwise. Set `setStrict(true)` in your action calls to opt in. ```csharp // This will throw if you have more than one button! await page.ClickAsync("button", new Page.ClickOptions().setStrict(true)); ``` #### 📍 New [**Locators API**](./api/class-locator) Locator represents a view to the element(s) on the page. It captures the logic sufficient to retrieve the element at any given moment. The difference between the [Locator](./api/class-locator) and [ElementHandle](./api/class-elementhandle) is that the latter points to a particular element, while [Locator](./api/class-locator) captures the logic of how to retrieve that element. Also, locators are **"strict" by default**! ```csharp var locator = page.Locator("button"); await locator.ClickAsync(); ``` Learn more in the [documentation](./api/class-locator). #### 🧩 Experimental [**React**](./selectors#react-selectors) and [**Vue**](./selectors#vue-selectors) selector engines React and Vue selectors allow selecting elements by its component name and/or property values. The syntax is very similar to [attribute selectors](https://developer.mozilla.org/en-US/docs/Web/CSS/Attribute_selectors) and supports all attribute selector operators. ```csharp await page.ClickAsync("_react=SubmitButton[enabled=true]"); await page.ClickAsync("_vue=submit-button[enabled=true]"); ``` Learn more in the [react selectors documentation](./selectors#react-selectors) and the [vue selectors documentation](./selectors#vue-selectors). #### ✨ New [**`nth`**](./selectors#n-th-element-selector) and [**`visible`**](./selectors#selecting-visible-elements) selector engines - [`nth`](./selectors#n-th-element-selector) selector engine is equivalent to the `:nth-match` pseudo class, but could be combined with other selector engines. - [`visible`](./selectors#selecting-visible-elements) selector engine is equivalent to the `:visible` pseudo class, but could be combined with other selector engines. ```csharp // select the first button among all buttons await button.ClickAsync("button >> nth=0"); // or if you are using locators, you can use First, Nth() and Last await page.Locator("button").First.ClickAsync(); // click a visible button await button.ClickAsync("button >> visible=true"); ``` ### Browser Versions - Chromium 94.0.4595.0 - Mozilla Firefox 91.0 - WebKit 15.0 ## Version 1.13 #### Playwright - **🖖 Programmatic drag-and-drop support** via the [`method: Page.dragAndDrop`] API. - **🔎 Enhanced HAR** with body sizes for requests and responses. Use via `recordHar` option in [`method: Browser.newContext`]. #### Tools - Playwright Trace Viewer now shows parameters, returned values and `console.log()` calls. #### New and Overhauled Guides - [Intro](./intro.md) - [Authentication](./auth.md) #### Browser Versions - Chromium 93.0.4576.0 - Mozilla Firefox 90.0 - WebKit 14.2 #### New Playwright APIs - new `baseURL` option in [`method: Browser.newContext`] and [`method: Browser.newPage`] - [`method: Response.securityDetails`] and [`method: Response.serverAddr`] - [`method: Page.dragAndDrop`] and [`method: Frame.dragAndDrop`] - [`method: Download.cancel`] - [`method: Page.inputValue`], [`method: Frame.inputValue`] and [`method: ElementHandle.inputValue`] - new `force` option in [`method: Page.fill`], [`method: Frame.fill`], and [`method: ElementHandle.fill`] - new `force` option in [`method: Page.selectOption`], [`method: Frame.selectOption`], and [`method: ElementHandle.selectOption`] ## Version 1.12 #### Highlights - Playwright for .NET v1.12 is now stable! - Ships with the [codegen](./cli.md#generate-code) and [trace viewer](./trace-viewer.md) tools out-of-the-box #### Browser Versions - Chromium 93.0.4530.0 - Mozilla Firefox 89.0 - WebKit 14.2 This version of Playwright was also tested against the following stable channels: - Google Chrome 91 - Microsoft Edge 91
